Equity [Abstract] |
MEZZANINE EQUITY AND STOCKHOLDER CAPITAL | MEZZANINE EQUITY AND STOCKHOLDER CAPITAL Preferred stock As of September 30, 2023, the Company's Amended and Restated Certificate of Incorporation (as amended, the "Certificate of Incorporation") authorized the Company to issue 20,000,000 shares of preferred stock, par value $0.0001 per share. There were zero and 3,000 shares of Series A Convertible Preferred Stock issued and outstanding as of September 30, 2023 and December 31, 2022, respectively. Shares of preferred stock may be issued from time to time in one or more series. The voting powers (if any), preferences and relative, participating, optional or other special rights, and the qualifications, limitations and restrictions of any series of preferred stock will be set forth in a Certificate of Designation filed pursuant to the Delaware General Corporation Law, as determined by the Company's Board of Directors. On November 11, 2022, the Company, entered into a Securities Purchase Agreement (the “Purchase Agreement”) with Mutual Fund Series Trust, on behalf of AlphaCentric LifeSci Healthcare Fund (the “Purchaser”), pursuant to which the Company issued on November 14, 2022, in a private placement transaction, an aggregate of 3,000 shares of Series A Convertible Preferred Stock, par value $0.0001 per share (the “Series A Preferred”), for an aggregate subscription amount equal to $300,000. This transaction resulted in $89,000 of issuance costs and a net subscription of $211,000 as of December 31, 2022. The Company determined that the Series A Preferred should be classified as Mezzanine Equity (temporary equity outside of permanent equity) and that the Series A Preferred more closely aligned with debt as the intent was for redemption by either the holder or issuer, most likely the issuer (the Company), due to the more favorable redemption terms. The Purchase Agreement required that the Company convene, no later than January 31, 2023, an annual meeting or special meeting of stockholders for the purpose of presenting to the Company’s stockholders a proposal (the “Proposal”) to approve a reverse stock split of its outstanding common stock (the “Reverse Stock Split”), with the recommendation of the board of directors that the Proposal be approved, and that the Company use reasonable best efforts to obtain approval of the Proposal. Additionally, the Purchase Agreement contained customary representations, warranties and agreements of the Company and the Purchaser, and customary indemnification rights and obligations of the parties. Pursuant to the Purchase Agreement, the Company filed a Certificate of Designation of Preferences, Rights and Limitations of Series A Convertible Preferred Stock (the “Certificate of Designation”) with the Secretary of State of Delaware on November 14, 2022 designating 3,000 shares out of the authorized but unissued shares of its preferred stock as Series A Preferred with a par value of $0.0001 per share and establishing the rights, preferences and limitations of the Series A Preferred. The Certificate of Designation provided, among other things, that except as otherwise provided in the Certificate of Designation or as otherwise required by law, the Series A Preferred would have no voting rights (other than the right to vote as a class on certain matters as provided in the Certificate of Designation). However, pursuant to the Certificate of Designation, each share of Series A Preferred entitled the holder thereof (i) to vote on the Proposal and any proposal to adjourn any meeting of stockholders called for the purpose of voting on the Proposal, and (ii) to 1,000,000 votes per share of Series A Preferred on the Proposal and any such adjournment proposal. The Series A Preferred should, except as required by law, vote together with the common stock (and other issued and outstanding shares of preferred stock entitled to vote), as a single class; provided, however, that such shares of Series A Preferred should, to the extent cast on the Proposal or any such adjournment proposal, be automatically and without further action of the holders thereof voted in the same proportion as the shares of common stock (excluding abstentions and any shares of common stock that are not voted) and any other issued and outstanding shares of preferred stock of the Company entitled to vote (other than the Series A Preferred or shares of such other preferred stock, if any, not voted) are voted on the Proposal. In addition, the Series A Preferred were entitled to customary dividends and distributions when and if paid on shares of the common stock and were entitled to the voting rights discussed above. The Series A Preferred had preference over the common stock with respect to distribution of assets or available proceeds, as applicable, in the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company or any other deemed liquidation event. The shares of Series A Preferred were convertible at the option of the holder, at a conversion price of $4.68 per share (as adjusted for the Reverse Stock Split), into shares of the Company’s common stock, at any time and from time to time from and after 15 business days following the earlier of (i) the date of the approval of the Proposal or (ii) the date the Company otherwise satisfies the Nasdaq listing requirements. The Company had the right to redeem the Series A Preferred at any time during the 15 business days following the approval of the Proposal (the "Company Redemption Period") at 120% of the stated value. Each holder of Series A Preferred had the right to require the Company to redeem all or a portion of the Series A Preferred held by such holder following the expiration of the Company Redemption Period at 130% of the stated value. In addition, the Company would automatically redeem all of the Series A Preferred within five business days following a delisting event as specified in the Certificate of Designation at 130% of the stated value. On January 17, 2023, the Company redeemed all outstanding shares of its Series A Preferred, for an aggregate of $360,000 paid to the Purchaser. The redemption payment represents 120% of the stated value of the Series A Preferred Stock pursuant to the Certificate of Designation. On January 17, 2023, the Company filed a Certificate of Elimination (the “Certificate”) with the Secretary of State of the State of Delaware with respect to the Series A Preferred Stock. The Certificate (i) eliminated the previous designation of 3,000 shares of Series A Preferred Stock from the Company’s Amended and Restated Certificate of Incorporation, none of which were outstanding at the time of filing, and (ii) caused such shares of Series A Preferred Stock to resume their status as authorized but unissued and non-designated shares of preferred stock. Common stock Pursuant to the Certificate of Incorporation, the Company is authorized to issue 150,000,000 shares of common stock, par value $0.0001 per share. Each share of common stock is entitled to one vote. The holders of common stock are also entitled to receive dividends whenever funds are legally available and when and if declared by the board of directors, subject to the prior rights of holders of all classes of preferred stock outstanding. The Company has never declared any dividends on common stock. On February 8, 2023, the Company's Board of Directors approved a 1-for-18 reverse stock split of the Company's outstanding shares of common stock. The reverse stock split was effected on February 10, 2023 at 5:01 p.m. Eastern time. At the effective time, every 18 issued and outstanding shares of the Company's common stock were converted into one share of common stock. No fractional shares were issued in connection with the reverse stock split, and in lieu thereof, each stockholder holding fractional shares was entitled to receive a cash payment (without interest or deduction) from the Company’s transfer agent in an amount equal to such stockholder’s respective pro rata shares of the total net proceeds from the Company’s transfer agent sale of all fractional shares at the then-prevailing prices on the open market. The number of authorized shares of the Company's common stock and the par value of each share of common stock remained unchanged. Unless noted, all common stock and per share amounts contained in the unaudited condensed consolidated financial statements have been retroactively adjusted to reflect a 1-for-18 reverse stock split. Issuance of common stock On August 12, 2021, the Company entered into a Sales Agreement (the "2021 Sales Agreement") with Cantor Fitzgerald to sell shares of the Company's common stock, from time to time, with aggregate gross sales proceeds of up to $50.0 million through an at-the-market equity offering program under which Cantor Fitzgerald will act as the Company's sales agent. Cantor Fitzgerald is entitled to compensation for its services equal to up to 3.0% of the gross proceeds of any shares of common stock sold under the 2021 Sales Agreement. During the nine months ended September 30, 2022, the Company issued and sold 143,770 shares of common stock at a weighted average per share price of $11.16 pursuant to the 2021 Sales Agreement for $1.5 million in net proceeds. During the nine months ended September 30, 2023, the Company issued and sold 34,589 shares of common stock at a weighted average per share price of $4.52 pursuant to the 2021 Sales Agreement for $0.2 million in net proceeds. On March 15, 2022, the Company entered into the Equity Purchase Agreement with Lincoln Park which provides that, upon the terms and subject to the conditions and limitations set forth therein, the Company may sell to Lincoln Park, at the Company's discretion, up to $30.0 million of shares of its common stock over the 36-month term of the Equity Purchase Agreement. Upon execution of the Equity Purchase Agreement, the Company issued 92,644 shares of its common stock to Lincoln Park as commitment shares in accordance with the closing conditions contained within the Equity Purchase Agreement. The issuance of these shares were specific incremental costs directly attributable to the proposed offering. The commitment shares were valued at $0.9 million and recorded as an addition to equity for the issuance of common stock and treated as a reduction to equity as a cost of capital to be raised under the Equity Purchase Agreement. Lincoln Park has covenanted not to cause or engage in any manner whatsoever, any direct or indirect short selling or hedging of the Company’s common stock. The Equity Purchase Agreement may be terminated by the Company at any time, at its sole discretion, without any additional cost or penalty. As of September 30, 2023, the Company has not sold any shares of its common stock to Lincoln Park under the Equity Purchase Agreement. On October 30, 2023, the Company delivered a notice of termination to Lincoln Park terminating the Equity Purchase Agreement. On October 27, 2023, the Company entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) with certain institutional and other accredited investors (the “Purchasers”), pursuant to which the Company agreed to sell and issue to the Purchasers in a private placement transaction (the “Private Placement”) (i) 10,652,543 shares of the Company’s common stock and (ii) with respect to certain Purchasers, pre-funded warrants to purchase 28,614,437 shares of common stock (the “Pre-Funded Warrants”) in lieu of shares. The purchase price per share of common stock was $2.245 per share (the “Purchase Price”) and the purchase price for the Pre-Funded Warrants is the Purchase Price minus $0.0001 per Pre-Funded Warrant. On November 1, 2023, the Company received gross proceeds of $88.2 million from the Private Placement, before deducting fees to the placement agent and offering expenses payable by the Company. Warrants As of September 30, 2023, the Company had equity-classified warrants to purchase an aggregate of 27,509 shares of the Company’s common stock outstanding, with an exercise price of $76.08. The exercise price will be adjusted in the event of issuances of common stock at a price lower than the exercise price of the warrants then in effect (the “Down Round Feature”). During the nine months ended September 30, 2023 and 2022, the Down Round Feature was triggered due to the price per share received from the issuance of common stock. The Company calculated the value of the effect of Down Round Feature measured as the difference between the warrants’ fair value, using the Black-Scholes-Merton option-pricing model, before and after the Down Round Feature was triggered using the original exercise price and the new exercise price. The difference in fair value of the effect of the Down Round Feature was immaterial and had no impact on net loss (income) per share in the periods presented. The exercise price will continue to be adjusted in the event the Company issues additional shares of common stock below the current exercise price, in accordance with the terms of the warrants.
